• Designed to API 650/653 recommendations
• weld inspection length, improves inspection times and reduces operator fatigue
• Integrated LED lights provide the required light intensity as specified by API and ASME inspection standards
• Screen glare and shadows from external light sources are eliminated
• Calibrated vacuum relief valve ensures the correct vacuum is generated, too high a vacuum can damage the vacuum box and cause injury to the operator
• Superior build quality with robust cast aluminum body
• Two-stage seal design to improve initial vacuum, especially on large lap welds
• Electric vacuum pump or compressor driven

Proper setup and operation of Inside Corner Vacuum Box Bubble Leak Testing equipment are essential for accurate and reliable weld inspections. Follow these steps to set up the testing process:
1. Select the Right Equipment: Choose a vacuum box that matches the size and type of inside corner welds you intend to inspect. Ensure it is compatible with the specific testing requirements.
2. Safety Precautions: Prioritize safety when working with testing equipment. Wear appropriate personal protective equipment, such as gloves and safety glasses, and ensure proper ventilation in your workspace.
3. Prepare the Weld Area: Clean and prepare the weld area to remove any contaminants, such as oil, grease, and rust, that could interfere with the inspection.
4. Prepare the Liquid Solution: Mix the liquid solution (typically a soapy water mixture) according to the manufacturer's recommendations. Ensure that it is evenly applied and covers the weld area.
5. Position the Vacuum Box: Place the vacuum box over the inside corner weld joint, ensuring it forms a sealed chamber. Seal any gaps or openings to prevent air leakage.
6. Connect the Vacuum Source: Attach a vacuum source to the vacuum box. Ensure that the vacuum source is capable of creating the necessary pressure differential.
7. Start the Vacuum Pump: Turn on the vacuum pump and create a pressure differential within the vacuum box. The pressure reduction will draw gas from any leaks in the weld.
8. Apply the Liquid Solution: Apply the liquid solution to the weld area inside the vacuum box. Be thorough in covering the entire weld joint.
9. Inspect for Bubbles: Carefully inspect the liquid surface for the formation of bubbles. Bubbles indicate gas escaping from leaks or imperfections in the weld.
10. Document Findings: Record and document any defects found during the inspection, including their location, size, and the severity of the issue.

To ensure precise and reliable weld inspections using Inside Corner Vacuum Box Bubble Leak Testing, consider the following tips:

1. Calibration: Regularly calibrate your vacuum box and testing equipment to maintain accuracy in defect detection.
2. Proper Liquid Application: Ensure that the liquid solution is evenly applied to the weld area to prevent false indications.
3. Pressure Differential: Monitor and maintain the correct pressure differential in the vacuum box to ensure consistent and accurate results.
4. Careful Inspection: Conduct a meticulous visual inspection, and if defects are found, follow up with appropriate repairs or further testing as needed.
5. Training: Ensure that personnel conducting the testing are trained and experienced in Inside Corner Vacuum Box Bubble Leak Testing procedures to maximize accuracy.
6. Documentation: Keep detailed records of weld inspections, including photographs and reports, for quality control and future reference.
